Small gem. Fits comfortably in the palm of your hand. Dark unknown kind of gem. Maybe someone else more knowledgable about this thing knows. There is someway you can unlock the inner fires of the gem which makes it glow with an orange light.
Family heirloom in the Blackwick family. They don’t really remember how they got it. They believe it brings luck though. Was given to Brienne when she set out from the village so she would have something to remember the family by.
